As you all know, Colin Kaepernick remains unsigned even as seemingly less-talented quarterbacks latch on to NFL teams. One of them is Blaine Gabbert, who lost his job to Kaepernick with the San Francisco 49ers last season yet signed a deal with the Arizona Cardinals.

Moving on from that peculiarity, we’re at the point of the NFL calendar where teams get to filling out their rosters now that they’re done with the draft but not quite ready for June minicamps. If Kaepernick doesn’t sign soon, one has to think that nothing is going to happen until training camp, when teams again start again looking for quarterbacks because of injury and ineffectiveness.

So are NFL teams even sending out feelers on Kaepernick? Yes, according to sociologist and longtime 49ers consultant Harry Edwards, who said three teams have contacted him about the former Super Bowl starter.

“They’ve asked, ‘Can he play? Does he want to play?’ ” Edwards told USA Today’s Jarrett Bell. “The last question I can’t answer. The first question, absolutely. If Kaep makes up his mind, he wouldn’t only go in and make a team, he’d put pressure on somebody to start.”

But informal chats with someone who is somewhat close to Kaepernick but doesn’t speak officially for him — Edwards reportedly has advised him over his career, though he told Bell that he hasn’t talked with him since early March — don’t necessarily rise to the level of serious interest.
